Research on Automatic Construction of Technology Classification System in Agricultural Field
[Purpose/significance]Nowadays,the field of agricultural science and technology is developing rapidly,and the disci-plines in the field of agriculture are diverse.However,the existing traditional classic classification system is not suitable for the current agricultural field,which shows the trend of interdisciplinary and integrated development.It is worthy of attention to construct an agricul-tural technology classification system suitable for the current situation of agricultural development.[Method/process]On the basis of classic traditional classifications,this paper integrates a variety of data sources,and constructs a set of agricultural technology classifica-tion system from both qualitative and quantitative perspectives,combined with the methods of subject word co-occurrence,citation cou-pling,and manual adjustment.This paper further expounds the rationality of classification from four aspects:scale,method,current sit-uation of agricultural discipline layout and development trend of agricultural field.[Result/conclusion]The classification method of ag-ricultural technology proposed in this study is reasonable and has certain applicability in the field of agriculture,and puts forward rele-vant suggestions on the development trend of current agricultural research and the construction of classification system.
